According to a CareerBuilder survey of more than 3900 workers, 75% said that they had applied for jobs and then not heard anything back.
Inconsiderate, unethical, unprofessional, disreputable, unprincipled - candidates react using different adjectives but the feeling is the same and no wonder - more than 8 out of ten candidates EXPECT to hear back from a company when they apply for a job regardless of whether the employer is interested in them or not.
I just think it's potentially costly to you in the future.
There are reasons why it happens, let's crunch some numbers.
According to an article in Wall Street Journal, about 80% of available jobs are said to never even get advertised - they're either allocated in-house or through trusted recruitment agencies and partners who recommend and supply talent, often without the need to advertise (by the way using such a service can make sense both for employers and candidates!)
Of the 1 in 5 vacancies that do make it to the job boards (if you accept the WSJ article’s claim), the average number of people who apply for any given position is 118 and just twenty-percent of those applicants get an interview.
